Aspects herein are directed to an apparel layer system configured to provide variable levels of insulation, warming, or air permeability. The apparel layer system comprises a first layer of material and a second layer of material both extending in a first planar direction. A third layer of material is positioned between the first and the second layers of material and is selectively affixed thereto. An adjustment mechanism coupled to the second layer of material can be mechanically manipulated to shift the second layer of material between different positions or states to achieve variable levels of offset between the first and second layers of material in the first planar direction and in a second direction perpendicular to the first planar direction.

The invention relates to a garment with a thermal insulation structure. The thermal insulation structure comprises a first insulation element with a first insulation layer and a second insulation element with a second insulation layer, wherein the second insulation element has a different initial shape than the first insulation element and the first insulation element is connected to the second insulation element. The second insulation element is deformed when the garment is worn by a pressure on an inner side of the thermal insulation structure, so that a contact area, in which the first insulation element contacts the second insulation element, is increased. The thermal insulation structure further comprises a third insulation element with a third insulation layer.

A protective garment comprises a thermal liner, a moisture barrier, and an outer shell. The protective garment includes one or more transferal portions located at predetermined areas to enhance evaporative heat transfer. In some embodiments, the transferal portions of the protective garment have Resistance to Evaporation of a Textile (Ret) of less than 20 m2 Pa/W.

A protective garment comprises a thermal liner, a moisture barrier, and an outer shell. A protective material is disposed on at least a portion of an exterior surface of the outer shell to enhance traction and thermal properties of the protective garment. In some embodiments, the protective material is disposed as one or more protuberances produced from a silicone material.

The invention provides a process for manufacturing a dynamically warm-keeping garment with a one-way moisture transferring function. The warm-keeping garment is made of a one-way moisture transferring fabric that includes a surface layer, a warm-keeping layer and a lining layer or includes the surface layer, a first warm-keeping layer, an intermediate interlayer, a second warm-keeping layer and the lining layer. The above technical solution addresses the following problems of traditional warm-keeping cotton clothes and down jackets: temperature loss caused by unsmooth sweat discharge; complex and difficult processing due to underarm zippers for venlilation; static damage and possible explosion of washing machines by air pressure due to air tightness during washing.

The present disclosure describes a multimodal adaptive textile with moisture-responsive flaps composed of a nylon/metal heterostructure, which can simultaneously regulate convection, sweat evaporation, and mid-infrared emission to accomplish heat transfer tuning in response to human perspiration vapor. A metal layer contributes to low-emissivity radiative heating and enhances the bimorph actuation performance. The multimodal adaptive mechanism expands the thermal comfort zone compared to traditional static textiles and single-modal adaptive textiles without any electricity or energy input.

An article of clothing of a shirt having a neck line, a first shoulder on a first side of the neckline, a second shoulder on a second side of the neckline, a first side extending from the first should to a bottom, a second side extending from the second shoulder to the bottom. An added layer of fabric is attached to an inside of the shirt from the neckline, the first and second shoulders and the first and second sides to the bottom. The added layer of fabric is inconspicuous and is a protection against cold temperature.

An active-insulation paneling component and garments including an active-insulation paneling component. The active-insulation paneling component includes insulated panels separated by gussets. The gussets are configured to expand upon an outward pulling force to allow the active-insulation paneling component and/or garment to expand even where the active-insulation paneling component and/or garment are not manufactured from elastic materials.

An adaptive textile that includes a plurality of a first fiber having a first expansion coefficient and a plurality of a second fiber having a second expansion coefficient. There is a difference between the expansion coefficient of the first fiber and the expansion coefficient of the second fiber; at least one of the first or second fibers is a twisted coil actuator; and linear displacement of the twisted coil actuator causes the adaptive textile to bend.
